2'9 (ZZZ whom it may concern.-

Be it known that I, SIMON W. WARDWELL, a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented new and useful Improvements in Controlling Meansfor Winding-Machines,of which the followingis a specification.

My invention relates to winding-machines, and particularly to the meansfor controlling their operation.

The object of my invention is to provide improved devices for startingthe machine and for stopping it automatically upon the breakage of thesupply or at the finish of the cop. The invention is fully set forth inthe following specification, illustrated by the accompanying drawings,in which Figure 1 is a front view of the winding-machine, showing therelation of the starting and stopping mechanism; Fig. 2, an enlargeddetail view of the braking device; Fig. 3, a detail view of thestopping-lever; Fig. 4:, an enlarged sectional view on the line 1 1,Fig. 1; Fig. 5, a detail view of the threading-guide, showing itsrelation to the stopping-lever.

The machine in general is of a familiar type known to those versed inthe art as the Universal winding-machine.

The main frame A supports bearings for the winding-spindle B andcam-shaft C, the latter carrying the cam (not shown) which reciprocatesthe thread-guide D. The thread-guide is carried in the traverse-frame E,the latter being pivoted on the cam-shaft C to swing to allow the guideto move away from the Winding-spindle as the cop is built up thereon.The devices shown at G and described in my pending application, SerialNo. 135,768, filed December 18, 1902, serve to apply pressure on thetraverse-frame E to resist the outward movement of the guide, and toprevent this pressure forcing the guide back toward the spindle a detentis provided on the frame E. I prefer to make this detent in the formshown and described in my pending application, Serial No. 211,204, filedJune 4:, 1904:, in which an arm 9, operated by a spring-pressedfinger-lever f, engages a V-shaped groove in the sector H through itswedge-shaped extremity e".

The sector H is pivoted at h on the main its spring.

frame A and besides serving as a track for the arm 6 to bear on performsthe additional func tion of a detent for the starting-leverJ when thelatter is thrown into position to start the machine. The lever J ismounted on a rockshaft j, the latter extending to the back of themachine and connected to engage the driving mechanism. For this latterany usual device may be used, preferably that shown and described in mypending application, Serial N 0. 211,205, filed June 4, 1904. With thisarrangement the driving-pulley is thrown in and out of engagement with asuitable clutch on the spindle B by a rock-lever on the shaft j. Therock-shaft j is operated by any suitable spring arrangement to turn inthe direction indicated by the arrow, Fig. 1, to release thedriving-pulley from the clutch. For operating the rock-lever I havepreferred to show a lever s, fastened to the rear end of the rockshaft1' and connected by a coiled spring 2? to the machine frame. Anothersuitable arrangement would be to provide a coiled spring on therock-shaft, held under torsion by having one end fast in the frame andthe other socured to the shaft. To engage the drivingpulley with theclutch, the shaft is rocked in the opposite direction by means of thestartinglever J, and the shaft is held in this position (see Fig. 1) bythe arm Z, engaging the extension h of the sector H. The arm Z extendsfrom the hub of the lever J and is formed at its lower extremity with alug Z, engaging a shoulder 7& on the extension of the sector H. Beyondthis shoulder is a bearing-surface /1 which rests on the lug Z when thelatter has been released from the shoulder so that the sector H isalways supported at its free end by the arm Z. The weight of the sectormaintains the lug Z and shoulder k in engagement, and when it is desiredto stop the machine it is only necessary to raise the free end of thesector-to release the arm Z and allow the shaft 1' to be rocked underthe action of To cause immediate arrestment of the winding-spindle andof the cam-shaft connected therewith, I provide a braking deviceconsisting of the brake m, adapted to engage a disk or collar 6 on thewinding-spindle.

The brake m is pivoted on an arm extending grooves (see Fig. 2) adaptedto pinch upon the correspondingly-shaped rim of the disk 5.

In order that the operation of the machine may be arrested upon thebreaking or running out of the supply, I provide a stoppinglever K,adapted to release the detent of the starting-lever J. The lever. K forlightness is preferably formed of wire bent in triangular form andsuspended at its apex on the free end of the sector H. One leg of thelever K is made heavier than the others by coiling the wire of thebase-piece about it and is formed at its extremity with a bearingbar isfor the thread, terminating in the curved hook 70 This bearing-bar ithangs adjacent the top of the tension device L and is adapted to besupported on the thread as it leads to the thread-guide. The other leg10' is reinforced at its extremity by bending back the wire a shortdistance before carrying it across to the leg 76. The tension device isof the usual form, having two opposed plates with alternating parallelbars bearing on the thread to sinuate its course. One of the plates 0 ismovable to adapt it to swing toward the other fixed plate, and bothplates are supported by a rod P, passing through cars at theirextremities, the fixed plate being held rigid by the screw q and themovable plate hinged on the rod. The rod P is bent at its upperextremity in a semicircular form (see Fig. 5) to form a guide forthreading the supply under the bearing-bar 7c and terminates in a loop19, passing around the bar Zr to serve as a limit to the movement of thelatter.

The cam-shaft C carries a disk 0 at its outer end, the latter formedwith a corrugated or fluted rim and rotating in the direction indicatedby the arrow. When the lever K is supported by the thread, as shown inFig. l, the leg Z0 of the lever hangs adjacent the face of the disk 0,"but when the thread breaks or runs out the weight of the leg Z3 carriesthe extremity of the leg Ir into engagement withthe disk and therotation of the latter moves the leverK bodily upward, raising thesector H and releasing the lever J.

In order that the relation of the lever K to the disk 0 may be such asto cause a quick and positive action of the stopping devices, I providemeans for adjusting the fulcrum of the lever on the sector H. As shownin- Fig. 3, the lever K is supported on a pivot-pin i, screwed into thehead z' of the stud t the stud screwing into the end of the sector H.The pivot-pin is arranged eccentric to the stud and the head of thelatter is knurled to adapt it to be grasped by the fingers. When thestud is turned slightly, the pin is moved toward or away from the disk 0to adjust the lever K in relation thereto. A check-nut i is provided toscrew against the sector to secure the stud vin position.

In machines of this class it is desirable to have a stop to operate whenthe cop or package has reached its predetermined diameter. For thispurpose I provide the member R, adjustable along the sector H and havinga beveled under surface which is engaged by a portion of thetraverseframe E to lift the sector and release the detent of the leverJ. The member R is preferably formed of sheet metal bent in the formshown in Fig. 4, with a hooked extension reaching up in the groove ofthe sector H and bearing on the bottom. To secure the member in positionon the sector, I provide the following novel means: A thumb-screw rengages the upper bent por tion of the member R and is bored to receivethe plunger r. This latter is formed with a head r fitting the largersection of the bore of the screw 1", and with a shank extending throughthe smaller bore for a bearing and riveted at its end to preventdisplacement.- Surroundingthe shank of the plunger is a coiled spring rbearing on the bottom of the bore and the head o and tending to forcethe plunger down on the sector H. The upper face of the sector isprovided with a shallow groove 7t, and the end of the plunger 9" is ofrectangular form to adapt it to fit the groove. The pressure of thespring r causes friction between the plunger and the sector H, and thisslight resistance renders the member more susceptible to fineadjustment. The member R may be moved the slightest degree with utmostprecision and owing to the frictional contact will remain stationaryuntil set against the sector H. This is accomplished by screwing thescrew 7" through the member, the lower end of the screw bearing on theshoulder formed by the rectangular end of the plunger and binding'thelatter in the groove /t*.

The operation of the machine is as follows: The thread is drawn from thesupply up through the tensions, carried over against the curved guideportion of the rod P, and bearing against the latter is directed underthe bearing-bar 7c. Thence it is led up through the eye of thethread-guide and secured to the winding spindle, the traverse framebeing placed in position for the guide to bear on the spindle. To startthe winding, the lever J is swung in the opposite direction from thatindicated by the arrow until the lug Z engages the shoulder [02, Fig. 1.The swinging of the lever J releases the brake from the disk 6 andthrough the arrangement at the back of the machine causes thedriving-pulley to engage the spindle B to rotate the latter, whichthrough suitable connections also drives the cam-shaft C. The lever K issupported in the position shown by the thread passing under the bar 7c;but when the thread breaks-or runs out the lever is released, allowingthe extremity to engage the disk 0, which carries it upward to releasethe arm Z. 'When the arm Z is released,the spring connected to the shaft1' rocks the latter to disengage the driving-pulley from its clutch, andthe brake ITS ' with the main frame sired- Automatic stopping deviceshave before been designed to operate in connection withwinding-machines, and I do not here claim the combination broadly; butwhat I do desire to secure protection for is the particular.
